Fun fact. There are no Apple stores in the Eastern District of Texas (which includes the wealthy northern suburban counties of Dallas.) From Denton (north of Fort Worth) to the Eastern suburbs of Houston on the Gulf coast, no Apple stores.
Apple has been careful about the expansion of their retail stores, and limited to upscale urban areas.
The customers have to have the cash and the geography has to have the density.
Even with that, all Apple products can be bought online.
However, the Apple Store provides great service. I buy my Apple products online, but I take the kids to the Apple Store to get MacBooks, iPads and iPhones.
Typically, it’s an expensive trip.
